General Idea

The performance of solar photovoltaic (PV) systems can degrade over time, we aim to provide a tool to check the performance. The user should input location and specifications of the system. Our app will then diagnose if the performance is acceptable.

We created a web app that allows users to check the status of their solar installations by evaluating if the energy production is at a normal state. Our application aims at providing a quick verification of the monthly energy production of roof top solar panels. The user will provide the following input:

1. Location of the solar panel: address
2. Size of PV: area in m2
3. Capacity kWp
4. 12 months of production data

The app looks up the estimations from sonnendach, compares the the input and returns:

1. Location on map
2. Status: ok or not ok
3. Monthly comparison of actual vs. reference as a bar chart
